Hi! Can you tell me, there is any kind of difference, between front axle, from Blazer (6 lug, 2 shock absorbers) and front axle from Suburban (8 lug, 4 shock absorbers), like shock absorbers brackets, brakes, max. load capacity, bearings, lenght, etc.? Bouth have diff. on the passenger side, 3.73 end ratio and they are GM 10bolt. Mine, have 1760 mm lenght (between flat surfaces, where the wheels are mounting). Just curious! I find also, a 14bff, from a 3500 pickup, with the same end ratio (3.73) and I wish to replace, my 14bsf, with that. Can I do that, with no problems (yokes, drive shaft, springs position, etc.)? My 14bsf, have 1700 mm lenght. What lenght have 14bff? Is from a 3500, with single rear wheels, 7.4L gas engine (454 cid) and MT. I ask you, because, the parts, are on the other side of the country (600 km) and I did't see them, yet. The owner, have a K5 (from where is the front axle GM) and buy the 3500, for engine, MT and front axle (Dana 60).
